Patented Mar. 21, .1916.

Application filed August 25, 1913,:Ser-ia1 No. 786,552. Renewed February 15., 1916. Serial No. 78,551.

To all whom it may concern:

Be .it known that I, ANDREW LOOHHEAD, a subject of the King of England, residing at Oakland, in the .county of Alameda and State of California, have invented certain new and useful Improvements in Door-Securers, of which the following is .a specification, reference being had to the accompanying drawings.

This invention relates to door securers and more particularly to a device of this character shown and described in Patent Number 1,033,255, issued to me July 23, 1912, the primary object of the present invention being to materially simplify the construction and therefore reduce the manufacturing cost of my original device, without sacrificing its efficiency or reliability in practical use.

The invention has for a further object to provide a door securer which may be easily and quickly applied to the latch keeper of the door and when in its operative position serves to hold the door closed and prevent unauthorized opening of the same.

The invention has for another of its objects to provide a device for the above purpose which may be conveniently carried in the pocket or traveling bag so that the traveler can always have at hand effective means for securely locking the door of his room in case the door is not provided with a bolt or other form of lock.

WVith the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which- Figure l is a horizontal section through the door casing and door illustrating the application of the present invention thereto; Fig. 2 is a section taken on the line 22 of Fig. 1; Fig. 3 is an enlarged fragmentary side elevation illustrating the cam member for actuating the door securing bar and showing said member in its locking position in full lines and in its release position in dotted lines: Fig. 4: is a detail perspective view of the body bar.

Referring in detail to the drawing, 5

designates the body bar of my improved door lock or securer which is formed at one end with a bend 6 designed to be inserted in the latch keeper of a door casing as clearly illustrated in Fig. 1. The bar 5 is provided adjacent its other end with a longitudinal slot 7 at one end of which the metal bar is struck outwardly beyond one face thereof to form a lug 8.

-.9 designates the movable door engaging bar which extends in substantially parallel relation to the body bar 5 and is provided upon one end with an angularly disposed lug 10 which is adapted to bear against the face of the door. A bolt 11 is mounted in the other end of this bar and extends through the slot 7 of the body bar 5. A washer plate 12 is arranged upon said bolt between the bars 5 and 9 to space the same.

A cam lever 13 is loosely mounted upon the end of the bolt 11 and is adapted to be rotated thereon, for which purpose, said cam lever is provided with a laterally projecting finger piece 1 1. The cam edge 15 of the member 13 is adapted to bear against the lug 8 at the outer end of the slot 7 in the body bar when said lever is moved from the dotted line position to the full line posi tion shown in Fig. 3. In this movement of the cam lever, it will be obvious that the bolt 11 is forced inwardly in the slot of the body bar, thereby also moving the bar 9 mounted upon said bolt longitudinally with respect to said body bar whereby the lug 10 is engaged with the face of the door and tightly clamped against the same as shown in Fig. 1, to prevent the door from rattling and securely hold the same against being opened by a person outside of the room or apartment.

From the above description it will be seen that I have greatly simplified the door securer over its original construction as disclosed in the patent above referred to.

The device may be more easily applied to the door and the door secured thereby than was the case with my former invention.

As the device consists of but two primary elements which are of simple form, it will be obvious that my invention may be produced at very small manufacturing cost.

Owing to the small proportions and compact arrangement of the several parts, the invention may readily be carried in the coat pocket without noticeably bulging the same.

While I have in the foregoing described the particular form and construction of the several elements employed, it is to be under 7 bodied within the spirit and scope of the instood that the invention iscapable ofvari- 'ous minor modifications therein and I therefore reserve the right to resort to all such legitimate changes as may be fairly .em-

comprising a supporting bar designed for engagement with the latch keeper of a door, said bar havinga longitudinal slot'in one of its ends and a lug atone end of said "slot, a

door securing bar, a bolt Carried by said bar movable in the slot of the supporting bar, and means mounted on said bolt cooperating with said lug to move the securing barilongi- I tudinally" into clamping engagementflwith' the door. i

Copies of this patent may be obtainefl for five cents each, 'by addressing'the Commissioneroffatents,
